Article abstract of DOI:10.1016/S0040-4039(00)76704-9

A pronounced asymmetric induction (d.e. = 95%) was observed during methylation of pyridinium salt 7 with MeMgI which led ultimately to (2R) 2-methyl-2,3-dihydro-4-pyridone 9. This result is best explained by assuming chelate-control during the asymmetric alkylation step.
